Which of the following is NOT one of the Six Ps of compartment syndrome?

The correct answer is polyuria, which is not one of the Six Ps of compartment syndrome. The Six Ps are a set of clinical signs used to identify and assess compartment syndrome, a serious condition that occurs when increased pressure within a confined space compromises circulation and function of the tissues within that space.

The Six Ps include:

1. Pain out of proportion: This refers to severe pain that is greater than what would be expected from the injury or condition causing the compartment syndrome.

2. Pallor: This indicates a pale appearance of the skin, suggesting reduced blood flow due to increased pressure in the compartment.

3. Pulselessness: This refers to the absence of a pulse in the affected area, indicating possible compromised circulation.

4. Paralysis: This represents the inability to move the affected extremity due to nerve compression from the increased pressure.

5. Paresthesia: This involves abnormal sensations (like tingling or burning) that may occur due to nerve involvement.

6. Poikilothermia: This describes the inability to maintain a normal temperature in the affected area, which can be linked to circulatory issues.

Polyuria specifically refers to excessive urination, a symptom
